scheduling is an important subject of production and operations management area. in flow-shop scheduling, the objective is to obtain a sequence of jobs which when processed in a fixed order of machines, will optimize some well defined criteria. the concept of transportation time is very important in scheduling. transportation can be done by robots. in situations that robots are used to transpor...

We study self-organized navigation in a heterogeneous robotic swarm consisting of two types of robots: small wheeled robots, called foot-bots, and flying robots that can attach to the ceiling, called eye-bots. The task of foot-bots is to navigate back and forth between a source and a target location. The eye-bots are placed in a chain on the ceiling, connecting source and target using infrared ...

Abstract. We study self-organized cooperation in a heterogeneous robotic swarm consisting of two sub-swarms. The robots of each sub-swarm play distinct roles based on their different characteristics. We investigate how the swarm as a whole can solve complex tasks through a self-organized process based on local interactions between the sub-swarms. We focus on an indoor navigation task, in which ...

The problem of deploying a team of flying robots to perform surveillance coverage mission over an unknown terrain of complex and non-convex morphology is presented. In such a mission, the robots attempt to maximize the part of the terrain that is visible while keeping the distance between each point in the terrain and the closest team member as small as possible. A trade-off between these two o...

AbsCrocr-Robotic manipulators wiU play a significant role in the maintenance and repair of space stations and satellites, and other f u m space missions. Robot path planning and control for the above applications should be optimum, since any inetedency in the planning may considerably risk the success of the space mission. This paper prrsents a global optimum path planning scheme for redundant ...

Endowing robots with the ability to plan their actions and motions will enable robots to assist people with a wider range of tasks in the real world. Robot planning can improve a robot’s usability and capabilities for a variety of applications, from manufacturing to medicine to home assistance to transportation to disaster response. Recent years have seen significant technical progress that has...

This work addresses the question whether active impedance control is key to a breakthrough for legged robots. In this paper, we will talk about controlling the mechanical impedance of joints and legs with a focus on stiffness and damping control. In contrast to passive elements like springs, active impedance is achieved by torque-controlled joints allowing real-time adjustment of stiffness and ...

Many algorithms have been proposed that create a path for a robot in an environment with obstacles. Most methods are aimed at finding a solution. However, for many applications, the path must be of a good quality as well. That is, a path should be short and should keep some amount of minimum clearance to the obstacles. Traveling along such a path reduces the chances of collisions due to the dif...

To serve as a platform for multi-agent research, the BYU MAGICC Lab has created a version of the game of capturethe-flag played in a maze environment that can be configured to model a variety of indoor and urban settings. Each competing team has mobile robots on the ground, a simulated UAV flying overhead, and a remote human commander. Since simultaneous low-level control of all robots is not p...

Our understanding of animal flight has inspired the design of new aerial robots with more effective flight capacities through the process of biomimetics and bioinspiration. The aerodynamic origin of the elevated performance of flying animals remains, however, poorly understood. In this themed issue, animal flight research and aerial robot development coalesce to offer a broader perspective on t...
